Ever since the invention of the laser over 50 years ago, scientists have been striving to create an x-ray version of the laser. Advances in extreme nonlinear optics now make it possible to efficiently upshift tabletop femtosecond lasers into the ultraviolet (EUV) and soft X-ray regions of the spectrum, to wavelengths as short as 8 Å.

This unique high harmonic (HHG) light source is ideally suited for host of applications in imaging and understanding how advanced materials function. A host of applications in nanoscience and nanotechnology have now been demonstrated using EUV HHG, including full-field microscopes with record 14nm spatial resolution, quantifying how nanoscale energy flow differs from bulk, measuring how fast a material can change its electronic or magnetic state, probing how spin currents can control and enhance magnetization in ultra thin films, and visualizing the dynamic band structure of material.

The combination of Focused Ion Beams with Scanning Electron Microscopes (FIB/SEM) have enabled accessing microstructural information at and below the surface in 3D. The need is growing for imaging and analysis of larger grained materials and metals in 3D as well as processing larger volumes of data for better statistical accuracy. Until recently, the available technologies have limited the volumes and depths of materials that can be analyzed at high resolution, ultimately restricting the insight into structural, crystallographic, and chemical properties. This is no longer the case. The introduction of Xe Plasma FIB/SEM technology offers unrivaled access to regions of interest deep below the surface – combining serial section tomography with statistically relevant data analysis. This also means that large volumes of interest identified by X-ray CT can be investigated in great detail.

Xe Plasma FIB/SEM technology enables dramatically improved material removal rates compared to traditional methods - while maintaining exceptional surface quality and high-contrast, ultra-high resolution imaging performance. We will discuss how Xe Plasma FIB technology opens the doors to new research applications such as the visualization and analysis of large grained polycrystalline metal samples whilst maintaining nanoscale resolution to investigate further the grain boundaries of these materials.

In addition to the ultra-high-resolution capabilities, the webinar will examine the wider potential of Xe Plasma FIB technology for a variety of characterization techniques such as performing 3D tomography, 3D EBSD, 3D EDX, as well as correlative tomography.

Watch this on-demand free webinar by Logging In or Signing Up below.

Two-dimensional (2D) materials are attracting significant attention due to their unique properties. The most famous example is graphene, an atomically thin layer of carbon atoms: but recently an entirely new family of 2D materials, early transition metal carbides and carbonitrides, was discovered.

The selective etching of the A-group element from a MAX phase results in the formation of these 2D layered materials, dubbed “MXenes”; of which eleven different carbides and carbonitrides have been reported to date. Not only are individual layers formed after exfoliation, but also multi-layer particles and conical scrolls with radii < 20 nm. DFT simulations have shown that the band gap of MXenes can be tuned from metallic to semiconductor (2 eV) by changing their surface termination, and their elastic constants along the basal plane are expected to be higher than that of the binary carbides. Oxygen or OH terminated MXenes are hydrophilic, but electrically conductive.

Recently, we reported on the intercalation of Ti3C2, Ti3CN and TiNbC with polar organic molecules, which resulted in an increase of the c lattice parameter of MXenes. When dimethyl sulfoxide was intercalated into Ti3C2, followed by sonication in water, that latter delaminated forming a stable colloidal solution that was filtered to produce MXene “paper”.

While at one point materials science may have been synonymous with metals, alloys, glasses, composites, and polymers; there can be no denying that the softer and smaller materials now play a critical role. Just as with nanomaterials, the field of biomaterials exploded onto the scene during the first few years of the previous decade, continuing to grow rapidly year-on-year.

At the interface between the life sciences and physical sciences, biomaterials is at the forefront of 21st century research; including topics such as regenerative medicine, tissue engineering, implantable devices, drug delivery systems, and DNA manipulation.

Materials Today is delighted to invite you to take part in our next free, online-only event, covering all aspects of biomaterials. Just complete the form below to take part.

Invited presenters

Bioresorbable electronicsJohn A. Rogers, University of Illinois at Urbana-Champaign

A characteristic feature of modern silicon integrated circuit technology is its ability to operate in a stable, reliable fashion, almost indefinitely for practical purposes. Recent work demonstrates that carefully selected sets of materials and device designs enable a class of silicon electronics that have the opposite behavior -- it physically disappears in water or biofluids, in a controlled manner, at programmed times. This talk summarizes recent work on this type of ‘transient’ electronics technology, ranging from basic studies of dissolution of the key materials, to development of components and systems with radio frequency operation, to invention of schemes for externally ‘triggering’ transient behavior. Emphasis is on bioresorbable forms of such devices, for use in non-antibiotic bacteriocides and other applications of relevance to clinical healthcare.

Biocomposites and devices with naturally derived polysaccharides
Marco Rolandi, University of Washington

The ability to precisely assemble biological and bioinspired molecules into organized structures has contributed to significant advances in bionanotechnology. These advances include materials, structures, and devices that interface with biological systems. Here, I will present three such examples with chitin nanofibers and derivatives. The first example is chitin nanofiber ink — a solution of squid pen β-chitin that self-assembles into ultrafine α-chitin nanofibers upon drying. The second example is chitin nanofiber ink fabrication — chitin nanofiber micro- and nanostructures made with airbrushing, replica molding, and microcontact printing. The third example is bioprotonics — complementary field effect transistors with proton-conducting chitin derivatives containing acid and base functional groups.

Atomic layer deposition for medical and biological applicationsRoger Narayan, University of North Carolina and North Carolina State University

Over the past four decades, atomic layer deposition has been successfully utilized for the growth of thin films of many classes of materials, including metal oxides, metals, polymers, and inorganic-organic hybrid materials. This talk will review the use of atomic layer deposition for growth of conformal thin films on medical device materials and biologically-derived materials. In particular, recent advances involving the use of atomic layer deposition for the development of biosensors, drug delivery devices, and implants will be considered. The commercialization of atomic layer deposition technology for medical applications will also be discussed.

While nanomaterials have shown great potential for electronic and photonic applications, it has been difficult to organize them onto surfaces for incorporation into functional devices. To address some of these challenges, we have focused on assembling nanoscale materials on surfaces with control over material location and crystallographic orientation. The first part of this talk will highlight our recent efforts in directing and patterning single-stranded DNA and DNA templates on substrates with micro- and nanoscale resolution. A number of different substrates were patterned by optical and e-beam lithography to create highly parallel arrays of meso- and macroscale DNA “origami” scaffolds. Using DNA templates encoded with multiple nanometer recognition sites, hierarchical assemblies were generated consisting of both organic and inorganic nanoscale materials. The latter half of the talk will highlight our current research efforts in developing high yielding chemistries to attach DNA to surface and biomaterials for biosensing applications and also the use of DNA to create switchable nanoparticle based probes.

Platforms for engineering functional three-dimensional tissuesSuwan Jayasinghe, University College London

The ability to manipulate and distribute living mammalian cells with control presents fascinating possibilities for a plethora of applications in healthcare. These range from possibilities in tissue engineering and regenerative biology/medicine, to those of a therapeutic nature. The physical sciences are increasingly playing a pivotal role in this endeavor by both advancing existing cell engineering technology and pioneering new protocols for the creation of biologically viable structures. The presentation will briefly introduce leading technologies, which have been fully validated from a physical, chemical and biological stand point for completely demonstrating their inertness for directly handling the most intricate advanced material known to humankind. A few selected biotechnological applications will be presented where these protocols could undergo focused exploration.

Advances in thin film deposition technologies and material development have enabled innovations in a wide range of industries. Examples of this are evident in microelectronics, display, energy, optoelectronics, bio-medical, and many other industries.

Decreasing film thicknesses and manufacturing complexities pose new challenges for academic and industrial researchers. As coatings become thinner, material properties such as elastic modulus, hardness, adhesion, and friction become increasingly difficult to measure. These difficulties are particularly relevant for industrial process and quality control, where reliable characterization of film properties during and after production is critical to ensuring high yield and a consistent final product.

Oxide films for dielectrics, metals and nitrides for electrodes and interconnects, and diamond-like carbon films for abrasion resistance are just a few prime examples where thin films are already employed and must be characterized. Controlled engineering of these thin films is essential and presents a challenge. Highly precise force, displacement, and positioning control are requirements for continued improvement in the measurement of properties and performance of these advanced materials systems.

In this webinar we will review many of the current challenges in thin film mechanical characterization and analysis and present new and existing techniques that offer significant benefits for such challenging problems.

Who should attend?

Researchers involved in the development, production, or mechanical characterization of thin films and coatings.

Element analysis of samples using scanning electron microscopes (SEM) is widespread in materials science. A scanning electron microscope (SEM) provides not only topological information via surface images but also compositional information. In most cases, the microscopist will use energy-dispersive X-ray spectrometers (EDS) to analyze sample radiation created through the microscope’s electron beam.

This webinar discusses a complementary method: The use of a separate X-ray source equipped with polycapillary optics attached to the SEM to excite the sample and to evaluate the fluorescence radiation produced. This is known as micro-X-ray fluorescence spectrometry, or micro-XRF for short. Bruker’s Micro-XRF for SEM uses the EDS’ silicon drift detector and signal processing chain to form a complete micro-XRF spectrometer.

Although this method has been known for a number of years, its use in combination with a SEM is not very common, even though it has a range of benefits to offer. Our experts will explain this powerful addendum to EDS, which allows users to combine

the light-element sensitivity of EDS with trace element analysis in the mid to heavy element range by micro-XRF to improve the accuracy of quantification, and

the surface sensitivity of EDS with the volume analysis capabilities of micro-XRF.

The discussion of the technique will be complemented by the presentation of a number of application examples. Participants will have the chance to take part in a Q&A session at the end of the webinar.

The Conference is a free online-only event hosted by Materials Today, covering all aspects of microscopy, and bringing you some of the many fascinating developments that are taking place around the globe. Following on from a highly successful conference on microscopy in 2012, Materials Today has again gathered together experts from across the field to present their research.

This conference will highlight some ground breaking achievements, from electron and charged ion microscopy, to scanning probe techniques, to ultraviolet, infrared and x-ray methods: any and all applications of microscopy are welcome at the conference.

Helium Ion Microscopy (HIM) is a recent addition to the charged particle microscope family. HIM works under the same principle as an SEM, with the critical difference being incident electrons replaced with helium ions. Owing to its atomically sharp source and the larger momentum of helium ions compared to electrons, a sub-nanometer probe size is realized. HIM offers many advantages over standard SEM, namely, better resolution (0.35 nm), higher secondary electron yield giving higher surface detail, the ability to control charging of insulating samples without the need for a sputtered conductive coating as well as the ability to sputter specimen atoms and modify the material.

We will present an overview of HIM and its imaging capabilities. The results of high throughput resist based lithography will be presented, as well as results from studies into various biological systems, and the fabrication of gold nanogap electrodes using helium ions to sputter gold.______________________________________________________________________________________________

Creating nanoscale architectures through imaging and manipulating materials at the nanoscale has been realized through the advent of scanning probe microscopy (SPM). From imaging single atoms to high-speed recording of dynamic molecular phenomena at the liquid-solid interface, SPM has triggered the field of two-dimensional nano-engineering thereby providing a route past conventional CMOS technologies.

In this presentation I will highlight the applications of SPM related techniques beyond direct imaging to address some key challenges in fabricating high-density nano-electronic circuits such as mapping charge transport across active nanoscale components ranging from carbon nanotubes, graphene to metal nanowires and optimizing their contact resistance with metal electrodes. Specifically, I will describe our recent experimental results at IBM Zurich on real space in situ mapping of molecular dynamics, optimization of molecular electronic properties through extrinsic manipulation with nanometer scale spatial resolution in liquids and building defect-free electronically engineered interfaces.______________________________________________________________________________________________

EELS and its Application in the Characterization of Low-Dimensional Materials
Rebecca Nicholls, University of OxfordLive Q&A: 25th April at 4pmBST (GMT 1)

Electron energy loss spectroscopy (EELS) can provide us with a variety of information, ranging from the identification of the elements present within our material to the way in which atoms are bonded. EELS carried out within (scanning) transmission electron microscope ([S]TEM) makes it possible to obtain information from thin films samples or individual nano-objects.

This presentation will start with an introduction to EELS and the information present within the spectrum. I will then discuss the benefits of combining experimental EELS data with other experimental techniques and with simulations. I will discuss several examples on low-dimensional materials ranging from monitoring the elemental composition of nanotubes whilst current is passed to identifying individual substitutional atoms in graphene.______________________________________________________________________________________________

Nanoscale Imaging and Analysis across the Cell-Nanomaterial Interface
Alex Porter, Imperial College LondonLive Q&A: 25th April at 5pmBST (GMT 1)

The transmission electron microscope (TEM) is a powerful tool for imaging and analyzing the structure and chemistry of biomaterials interfaces with high energy and spatial resolution. This technique can provide detailed information about fundamental processes, such as chemical speciation of materials or mineralization, occurring at these interfaces. This analysis can provide insight into mechanisms of bioactivity or implant failure, how the toxicology of nanoparticles relates to their physicochemical properties or about tissue pathologies, such as osteogenesis imperfecta or neuro-degenerative diseases. These methods can also improve our understanding of the mechanisms by which hard tissues become mineralized during bone development. However, these methods are challenging to employ. The challenge is to probe accurately, with sufficient resolution, the chemistry and structure of the inorganic and organic phases simultaneously. The integrity of the organic phase and the interface must also be preserved and adequate contrast must be achieved between the individual components.

This seminar will discuss the results of studies in our laboratory where we have applied state-of-the art transmission electron microscopy techniques to study the biostability of a set of engineered nanoparticles with varied physicochemical properties in the cellular environment. Application of new techniques to study the cell based mechanisms of neuro-degeneration and bone mineralization will also be discussed.______________________________________________________________________________________________

The global need for sustainable energy production is pushing scientific research towards the development of inexpensive solar cells which can compete with established commercial silicon-based technologies. In particular polymer-inorganic hybrid solar cells based on nanostructured photoanodes have the advantage of low production costs and scalable solar power conversion, but exhibit relatively low efficiencies generally attributed to the deleterious effect of grain boundaries and interfaces on carrier diffusion lengths and recombination times.

By investigating inorganic photoanodes using high resolution electron microscopy techniques we are able to determine crystallography, morphology, surface and interfacial properties, which are essential for device optimization. I will discuss the case of TiO2, ZnO, and SnO2 photoanodes. I will also report on the 3D characterization of cross sectional solar cells by electron tomography, and the development of a quantitative approach to describe the fine-scale architecture of the solar cell.______________________________________________________________________________________________

Observing the Nanoworld: Electron Microscopy in the 21st Century
Valeria Nicolosi, Trinity College DublinLive Q&A: 26th April at 5pmBST (GMT 1)

With aberration correction, the world of electron microscopes has become sharper, more detailed and more interesting - much like the world of a short-sighted person trying on glasses for the first time. This seminar will start by briefly reviewing the developments that have made improved visualization possible, the development of electron microscopes and the new era marked by the development of aberration correctors for Transmission Electron Microscopes (TEMs).

Among the first materials to have benefitted most from these advances are inorganic nanowires made up from molybdenum, sulfur and iodine (MoSI nanowires). Other nanomaterials which have been at the centre of the most advanced nanotechnology research and that have most benefitted from recent advances in electron microscopy are graphene and graphene-like mono-atomic crystals. Aberration correction had allowed us to work to very low acceleration voltages, well below the knock-on threshold of the nanomaterials under investigation. This work will show how high angle annular dark field STEM allowed us to identify low-atomic number individual adatoms, vacancies and molecular-scale adsorbated in single-layer atomic crystals in which the nearest neighbors are 1.45 Å apart.______________________________________________________________________________________________

Explore the brand new technology of multiple ion beam microscopy, from the science to the first emerging results

The advance of nanotechnology requires fabrication techniques that can produce functional features on ever-smaller length scales. Techniques such as focused ion beam (FIB) microscopy are widely used in materials science to image surfaces and produce features on the nanoscale. In FIB, a beam of ions is scanned across a sample surface, and the material which sputters from the surface is detected in order to form an image. Due to the removal of material from the surface by sputtering, the ion beam etches out features in the sample surface which may be directed in the desired pattern.

The strive for decreasing feature sizes in plasmonic research, lithography, semiconductor technology and materials development leads to a need for instruments that enable rapid prototyping of such structures and simultaneous high resolution imaging for process control. The new gas-field ion-source technology (GFIS) offers the capability of combining atom-probe sized helium and neon ion beams (multiple ion beams) in one system for exactly these purposes. By adding a gallium FIB column, the request for high ablation rates is also addressed and completes the nanofabrication length scale from micrometers to below 10 nanometers.

This webinar explains the technology, presents first application results from leading research and applied science and gives an outlook on the potential of the technology.

Heat and noise in graphene: Unique properties and practical applications

Unique electronic properties of two-dimensional (2D) graphene originate from its unusual linear Dirac-cone dispersion. Phonons – quanta of lattice vibrations – in 2D crystals also reveal features different from those in bulk materials. In 2008, we discovered that the phonon thermal conductivity of suspended graphene can be exceptionally high – exceeding that of the basal graphite planes.

This presentation will review the results of optothermal Raman measurements, and describe practical applications of graphene in the thermal management of electronics. We will also discuss graphene electronic applications that do not require an energy band-gap including graphene-on-diamond interconnects with exceptional current-carrying capacity, low-noise graphene transistors for analog electronics and communications, phase detectors and selective gas sensors implemented with pristine graphene.

Controlled synthesis of colloidal nanoparticles: How high quality can benefit new discoveries

Synthesis of colloidal nanoparticles with tailored properties provides the foundation for exploring their applications in many promising areas, such as energy harvesting/conversion/storage, catalysis, electronics, etc. In this presentation, I will highlight a number of guidelines that allow us to engineer the critical nucleation steps involved in the growth of colloidal nanoparticles by taking the synthesis of silver nanoparticles with controlled sizes and morphologies as an example.

In the second part of the presentation, reversing size-dependence of optical properties of the synthesized silver nanoparticles and exceptional tetragonal crystalline symmetry of the silver nanowires will be highlighted to shed a light on how to use the well-synthesized nanoparticles as a platform to discover the unique properties associated with nanometer dimensions.

Boron nitride (BN) nanomaterials, i.e. nanotubes and nanosheets, have long been in a shadow of their popular carbon (C) cousins. However, recently, these exciting nanostructures have started to attract the full attention of materials scientists and engineers. NanoBNs are much more thermally and chemically stable compared to their C counterparts, while possessing approximately the same values of mechanical strength and thermal conductivity. Specific features of these nanomaterials include stable electrical insulation and radiation protecting properties. Therefore, nanoBNs are rich in exciting structural and functional application potentials.

For many years our group at NIMS, Tsukuba, Japan, has been studying and utilizing BN nanotubes and nanosheets in various fields, from reinforcing agents in polymers, ceramics and metals, to field-emitting and lasing applications. In this talk I will review the rich field of BN nanomaterials, particularly highlighting the new and booming field of “white” BN graphene.

The author is grateful to many past and present colleagues at NIMS for their tremendous contributions to the subject of this talk.

Dipeptide Hydrogels

Dave J. Adams, Department of Chemistry, University of Liverpool

Low molecular weight gelators (LMWG) form gels by the self-assembly of the LMWG into long fibres. These fibres entangle and, at a suitable concentration, lead to the network that gives rise to the solid-like properties of the gels. Many LMWG exist, with very different molecular structures. Paradoxically, it is also clear that slight changes in molecular structure can result in a LMWG becoming a non-gelator. Linking the molecular structure to the mechanical properties of the gels is difficult. One reason for this is that it is becoming increasingly clear that the method of assembly is a critical parameter in determining the properties of the gel. The self-assembly for LMWG can be induced by a variety of stimuli including pH, temperature and solvent polarity. Each of these methods can lead to a different self-assembly pathway. Here, we describe the formation of hydrogels from dipeptide-based LMWG. Depending on the assembly process, gels can be prepared which have widely differing properties. We will show how the properties of the gels can be controlled.

Our next webinar will feature an overview of current FTIR microscopy and imaging techniques for polymer analysis and also introduce Agilent’s new “sample preparation free” methodology; featuring industrial examples of how this technique can be applied to solve real world problems.

This webinar will introduce a new “preparation free” approach to polymer film and laminate chemical micro-imaging using Agilent’s “live ATR imaging” with enhanced chemical contrast.

Focusing on the microscopic to gain a better understanding of the macroscopic is the fundamental process many scientists go through in the pursuit of uncovering many of life’s challenges; be it to develop new materials that mimic human tissues and organs or in the race to find new and sustainable energy sources, microscopy in its many shapes and forms plays an influential role.

The phenomenal rise and interest in nanotechnology has helped fuel the many remarkable developments in microscope technology; the continual demand to investigate ever smaller and more complex molecules at increasingly higher resolution pushes the frontiers even further. Conventional analysis has told us something about what the samples are and the environment they find themselves in, we now need to know how they interact with one another and their surroundings.

This virtual conference brings to you some of the fascinating developments in microscopy. From optical and fluorescence microscopy through electron microscopy and the scanning probe, tunneling and atomic force microscopes.

Next-generation materials research is highly dependent on the development and application of innovative nanomechanical testing techniques. The utilization of nanoindentation at elevated temperatures is a growing area of research used to accurately determine nanoscale mechanical or tribological behavior at, or near, a material’s operating or processing temperatures. These hybrid techniques are extremely valuable for quantitatively determining temperature-dependent mechanical properties and conducting incipient plasticity, creep, phase transformation and glass transition studies.

This webinar provides an overview of recent advances in elevated temperature nanoindentation and highlights several application areas.

For anyone interested in materials characterisation on the electron microscope, this webinar is a must-see!

Launched in April this year, the Oxford Instruments AZtec nanoanalysis system incorporates the ideas of two leading visionaries in the microanalysis world. For Peter Statham, the Research Director at Oxford Instruments, AZtec is the fourth generation EDS microanalysis system, one that takes accuracy of analysis to a new and higher level. For Niels-Henrik Schmidt, founder of HKL Technology, AZtec is yet another step in his mission to evolve EBSD from a research topic to a mainstream tool for materials characterisation.

In this webinar you can hear both in conversation with the Editor of Materials Today about the trends they have identified in microanalysis, how customers provided critical insights into the way people actually worked in practice, and how emerging technology enabled them to specify a product that was so revolutionary.

Some of the topics covered will include:

How results once only achievable by experts after several hours work can now be visualized by anyone in real-time

How investigations at the nanoscale are made not just possible, but practical

How new mapping techniques brings new levels of certainty, clarity and detail

How to provide the accuracy required for standardless analysis

How to unravel the complexity of EBSD analysis to allow users to focus on their results and not their instrumentation

The benefits of a truly integrated approach to EBSD and EDS

How people working in multi-skilled, multi-user laboratories can fit in to corporate standards yet maintain working flexibility
